EM6325CXSP5B-1.3+

Supervisors Overview

The EM6325CXSP5B-1.3+ is an ultra-low current reset circuit manufactured by EM Microelectronic, designed for portable and battery-operated devices. It monitors supply voltage between 1.5V and 5.5V and generates a reset signal after a fixed timeout period once the voltage exceeds the threshold. This specific variant features a manual reset input (MR) with an internal pull-up resistor. The device operates within a temperature range of -40°C to +125°C and offers high reset threshold accuracy of ±1.5%. It provides three output options: active-low push-pull, active-low open-drain, or active-high push-pull. The circuit ensures valid resets down to 0.9V and includes immunity to short negative transients.

Supervisors Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage and package type. Confirm that the ordering code matches the required output polarity and reset timeout specifications. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with the target operating temperature range and supply voltage requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when ultra-low current consumption is critical for battery life extension in portable applications. Choose based on the specific threshold voltage requirement from the available eleven options. Consider the manual reset feature if external user intervention is needed to trigger a system restart. Evaluate the package size constraints, as small SC70 and SOT23 packages are available for space-sensitive designs.

Supervisors Part Context

The EM6325 series is part of EM Microelectronic's portfolio of reset circuits offering flexibility through various configurations. It is designed to replace discrete solutions by integrating voltage monitoring, delay timers, and reset generation into a single compact IC. The series supports a wide range of supply voltages and thresholds, making it suitable for diverse electronic systems requiring robust power management supervision.

Supervisors FAQ

What is the purpose of the MR pin?

The MR pin allows for manual assertion of the reset signal when pulled low, providing an external means to force a system reset independent of the supply voltage monitoring.

How does the circuit handle negative voltage transients?

The EM6325 is specifically designed to be immune to short negative transients on the VDD line, preventing false reset triggers during brief voltage dips or noise events.
